PREPARATIONS FOR START UP
Control that the nozzle (45° spray angle) applied is suitable for the
boiler potentiality. The table shows the delivery rates in kg/h of light
oil with respect to the nozzle size and the pump pressure (normally
12 bar). It should be remembered that 1 kg of light oil is equivalent
to approximately 10.200 kcal). Make sure that the retum pipe in
the tank has no obstructions, e.g. gate valves, closed plugs etc.
Any eventual obstruction would cause a breakage in the sealing
surface situated on the pump shaft. Close the main switch and the
boiler thermostats in order to start up the motor and the ignition
transformer and, after approximately 10 seconds, the electric valve
will cut in and expose the photoresistant cell to a source of light until
the burner stops (shut down). When the pipelines have been filled
up (and when fuel has come out of the nozzle), stop the burner and
put the photoresistant cell back in its seat.
Note: Should it be necessary to purge air, this can be done by
loosening the special fitting which the pump is provided
with (see 0002900680).

STARTING UP AND REGULATION
By acting on the regulating cam of 1st flame (see drawings n°
0002932270) set the 1st flame air shutter to let in an amount of air
deemed to be necessary for burner operation with 1st flame. Close
isolating switch and start the burner. With the burner running on 1st
flame adjust, if necessary, the amount of combustion air by acting
on the regulating cam.
Stop the burner and then staff it again to be sure that ignition takes
place correctly. Open isolating switch to stop the burner and con-
nect the terminals of the thermostat of 2nd flame. Now connect the
burner again: it will staff with 1st and 2nd flame. With the burner
running on 2nd flame adjust, if necessary, the amount of combu-
stion air means of the regulating cam. The burner is provided with
a regulating cam of combustion head. Make the regulation so as
to obtain Co
from 10 to 13% with smoke number not exceeding 2
2
of Bacharach scale.
